Parse Url As Defined In Rules

See rules for urlManager defined in config/main.php

...
'urlManager' => array(
	'urlFormat' => 'path',
	'rules' => array(
    	'<controller:\w+>/award-benefits' => '<controller>/Award_Benefits',
	),
),
...

Is there any function exists in framework to get actual mapped url for controller/action-method?

I'm trying to build sitemap.xml for website. So, all action methods I'm getting from controller class is like actionAward_Benefits and I want it parse it as defined in rules like award_benefits.
